    Subject[PATCH AUTOSEL 4.14 108/371] regulator: pv88080: Fix array out-of-bounds access
    Date
    From: Axel Lin <axel.lin@ingics.com>

    [ Upstream commit 3c413f594c4f9df40061445667ca11a12bc8ee34 ]

    Fix off-by-one while iterating current_limits array.
    The valid index should be 0 ~ n_current_limits -1.

    Fixes: 99cf3af5e2d5 ("regulator: pv88080: new regulator driver")
